Installation Cost

Mini-Split Installation Cost

Mini-split price depends mostly on how many zones you need. Here is roughly what one costs to install, using current national averages.

SystemTypical installed cost (U.S. average)
Single-zone mini-split (installed)$2,500 - $6,000
Multi-zone system (installed)$6,500 - $15,000+
Each added indoor head$400 - $1,800

Per Angi and HomeAdvisor (2026): mini-split installs average about $3,000 and range $2,000 to $14,500. Single-zone systems run $2,500 to $6,000; multi-zone $6,500 to $15,000+. NYS Clean Heat and utility rebates can offset a large share. Brand, efficiency, and number of zones drive the price.

Installation

Mini-Split Installation

Every LG mini-split we install is sized to each room or zone, then mounted, vacuumed and leak-checked, charged to spec, and set up with proper line-set, electrical, and condensate drainage. Done right, a ductless system is quiet, efficient, and draft-free.

We design single-zone or multi-zone layouts to fit your home and explain NYS Clean Heat rebates. See our ductless mini-split installation page or browse all AC mini-split brands.

Repair & Maintenance

Mini-Split Repair & Maintenance

A head not cooling, water dripping, an error code, or ice on the lines? Our factory-trained technicians diagnose and repair LG mini-splits fast, with 24/7 emergency service across Suffolk and Nassau County, checking refrigerant, the compressor, boards, and drains.

Cleaning the filters and coils and clearing the condensate line each year keeps a mini-split efficient and healthy. See our AC maintenance page.

Replacement

Mini-Split Replacement

When a ductless system is on R-22, failing, or undersized, replacing it with a modern inverter LG mini-split can cut bills and add zones. We will tell you honestly whether to repair or replace and design the right layout.

We handle removal, the new heads and condenser, refrigerant, and rebates, all with a free estimate up front. Want a ducted system instead? See our heat pump and central AC brands.

When To Call

Signs Your Mini-Split Needs Repair

Catching these early usually means a smaller, cheaper fix. Call us if your LG mini-split shows any of the following:

  • A head not cooling or heating
  • Water dripping from an indoor unit
  • Ice on the outdoor unit or lines
  • An error code on the head or remote
  • Weak airflow or a musty smell
  • Short cycling, or the system not starting
  • Grinding or buzzing from the outdoor unit
  • Rising energy bills
When To Replace

Signs You Need a Replacement

Repair is not always the smart money. It is usually time to replace when you see:

  • The system is 12-15+ years old
  • It still uses R-22 refrigerant
  • Repairs are getting frequent or expensive
  • It can no longer keep up in heat or cold
  • You want to add zones or higher efficiency
  • Rising bills as efficiency drops
